DRAWING-PEN.

Specification of Letters Patent.

Patented July '7, 1908.

Application filed September 16, 1907. Serial No. 393,139.

To all whom it may concern:

Be it known that I, CHARLES FrrzsIMMoNs, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Drawing- Pens, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention refers to improvements in drawing or ruling pens and is designed to provide a pen having the usual adjustable double blades which may be used with equal facility in drawing along a straight edge, or as an ordinary writing or lettering pen.

The invention consists in so constructin the tips or points of the blades that they wil be extreme y flexible, very thin and tapering, and more or less closely adjacent to or in contact with each other for some distance backwardly from the points, whereby to se cure the desired resiliency and flexibility to render possible manipulation and use of the pen in the manner indicated.

Referring to the drawings: Figure 1 is a view, in side elevation of the pen made in accordance with my invention. Fig. 2 is a plan view of Fig. 1. Fig. 3 is a view similar to Fi 2. Fig. 4 is a perspective View of the comp ete pen.

The blades 2, 2, are provided with the handle 3 in the usual manner and adjusted toward or from each other by means of the usual thumb screw 4 and the resiliency of the blades themselves, as will be readily understood. At their ends, the blades are narrowed by grinding away the metal at each side of the blade, as indicated at 5, leaving the long tapering tip 6 for each blade, very thin and narrow and adapted to be brought into contact each with the other by the thumb screw, as indicated in Fig. 1. The thickness of the blades are likewise reduced so that they will be flexible backwardly from their points, say one quarter inch or more, and when thus constructed the pen when filled with ink may be used as a writing pen and held by the user in such a manner as to utilize the flexibility of the pen on the paper and to cause the ink to flow readily.

Considerable skill in writing may be acquired by ractice and the vertical lines and horizontal ines may be made in different de-/ grees of thickness, as in shading. The pen is thus capable of greatly extended use both as a drawing and writing instrument.

In Fig. 3 the blades are shown as slit backwardly for a short distance as indicated at 7 in the same manner as with the ordinary writing pen, which further increases the flexibility or pliability.

It will be observed that the storage capacity, being much greater than that of the ordinary pen, will facilitate its use and reduce the number of necessary fillings.

The exact construction or design of the tips of the blades may be changed or varied by the skilled mechanic, depending on the work in view or other conditions, and I do not desire to be limited to the exact construction shown and described.

What I claim is:

1. A drawing pen provided with terminal blades having their ends narrowed in width and reduced in thickness and adapted to be brought together at their tips and to bear against each other for some distance backwardly from their .points, substantially as set forth.

2. A drawing pen provided with terminal blades having their ends narrowed in width and reduced in thickness and adapted to be brought together at their tips and to bear against each other for some distance backwardly from their points, and provided with an adjusting thumb screw, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES FITZSIMMONS.
